Prove an algebraic formula to shew that with a continuous load of uniform intensity passing over a beam A B, such as when a long train passes over a bridge A to B, the maximum shearing stress to any point K of the beam occurs when the part A K is fully loaded while the part K B is entirely unloaded ; and that the magni- tude of the stress is proportional to the square of the distance of K from the point A.
